Q.Braided Hibiscus tree in my yard
I have a Braided Hibiscus tree in my yard (zip code 01235) and was wondering if I put insulation down around the base and the wrap the tree in burlap, would that make it survive the winter months?
Hardy hibiscus plants need little care over winter and are hardy to zone 5 with no protection outdoors, though you may add mulch if you like. The tropical varieties are the ones that require growth indoors over winter. Tropical varieties must be grown in containers and overwintered indoors. These plants will not tolerate more than a night or two of light freezes. Even one hard freeze (below 25) could kill the plant.
Generally, braided hibiscus plants are of the tropical variety (namely Chinese hibiscus). Therefore, it is probably better to relocate the plant in a container for overwintering inside. You can, however, try to insulate and cover the tree but keep in mind that there are no guarantees this will work.
